.citizen of the United States, residiiig at li'ilhes-llarre, county of Luzerne, State ofpump used to remove Water or the like from the bottoni'of'a mine shaft.

' It is well known in pumping.operations in mines that it is coniinoi' practice to carry the exhaust. from the steam puinp tothe water inlet of the pump to assist the'fiow (it w: her to the pump and it has; Frequently lmppened when all-the water hasbecrrremoved from the mine shaft that the hot exhaust which is then del vered directly to the pump cylinder renders the valves and other. like parts inoperative.

IH'Iny present invention I have devised a ally coines to a. stop as soon as the water drops below the level of the erd ot the suction pipe and thereby damage otlhe pumpor its parts is eliminated. I It further consists of other novel features fully set forth. For the purpose of illustrating niy invention I have shown in the accompanying cut pro erred by me, since the same has been found in practice to give satisfactory and v of construction, -allas will be hereinafter drawin one form thereof which is at presreliable results, although it is to be under stood that the" various'instriiinentalities of which my invention consists can be VaIlously arranged and organizedand that -Referring to the drawings, 1 designates the frame work of a mine shaft and preferably the lower end of the same adjacent the bottom and upon which at a'soitable place -is mounted a steani'puinp 2 provided with the usual water inlet 3 and discharge outlet Specification of Letters Patent. -Pgtt;gnted Dec lei, Application filed May er, 1909.
